They sent me out some "classic" strips high priority and I expect them here tomorrow and I will do some side-by-side and alternate meter testing. As with any 2 instrument measurements it is impossible to know which one is more accurate without a control solution and I don't think I have any. That was another change now that I think of it - there are three control solution ranges on the bottle as if they now make 3 different control solutions (low, normal and high). I didn't ask about that. I looked at the insert and there's nothing to warn their users that the new product may not be FDA certified for their device so I'm not sure how they expected consumers to know since they just sent out the new strips as a direct replacement. There was accuracy info in the insert and it looked to me that these strips might be more accurate - on paper. It may be that the accuracy might be better at some ranges so, it's entirely possible that some reading could be off and the better one might just be the new strips. This may end up much ado about nothing but, at the very least, it was very poorly done.
